Its a process, its not simply by gathering people into BTC and making it as their currency, it will take tons of years before people completely jumps into Bitcoin, but I don't think that people would likely to make BTC as their currency right away, there will be a lot of doubts and arguments and I don't think that they are ready yet for this kind of change, lets take it slowly and let the process go its way.
Agree. Not everyone is accustomed to using digital or electronic cash for their daily purchases. Fiat currency has had a deep impact on everyone's lives for many years. For people to use Bitcoin as a currency, there needs to be confidence in it, the same way there is for the USD. Considering the regulatory uncertainty surrounding Bitcoin and other cryptocurrencies, it's very unlikely people will gain confidence in them anytime soon. However, as time goes by, Bitcoin will improve in many ways from being scalable to being regulatory compliant across diverse cryptocurrency exchanges.
As Fiat currency decays, people will shift their attention towards other alternatives that will help maintain their spending power. This means, that people will adopt Bitcoin and other cryptocurrencies for their own needs, especially because such medium of exchange does not rely on middleman or a central authority. Despite this, one needs to slowly introduce people into Bitcoin to help accelerate the process of adoption within the mainstream world. Just my thoughts
